[Pw_forum] Intel MPI

[joaquin peralta]

Me and Claudia

are using intelmpi 4.0 in http://cystorm.ece.iastate.edu with a very good
performance .. but we are not sure now ... let me explain :

We use a surface of Al with 81 in 128 cpus using intelMPI and openMPI 1.4

The compilations options (make.sys), input file and output files are in this
page (sorry for use my page but was the more fast) :

http://www.lpmd.cl/jperalta/index.php?n=Site.QE-Cystorm

Probably is not a good test, because we detect after that the cluster
schedule manager (torque) was not work properly with intelMPI and was very
probably that some external works are using process in the open-mpi running.
Look this thread about schedule-manager and intelMPI
http://software.intel.com/en-us/forums/showthread.php?t=76537

Right now the cluster is under a upgrade, sure when we can do more test we
shared that.

Best Regards
Joaquin and Claudia.
